The Hadean eon represents the time before fossil record of life on Earth; its upper boundary is now regarded as 4.0 Ga (billion years ago).Other subdivisions reflect the evolution of life; the Archean and Proterozoic are both eons, the Palaeozoic, Mesozoic and Cenozoic are eras of the Phanerozoic eon.► Shows little variation in the spatial pattern of RSL change in the area over the last ca. This clock representation shows some of the major units of geological time and definitive events of Earth history.
The geology or deep time of Earth's past has been organized into various units according to events which took place.
► Analyses shoreline altitude data using Ordinary Kriging and Gaussian Trend Surface Analysis.
► Depicts an elliptical pattern of RSL change around a centre in the South East Grampians.
The patterns for the most widely occurring shorelines were analysed and found to be similar and common centre and axis models were developed for all shorelines.
The analyses described provide models of the spatial pattern of Holocene RSL change in the area between ca 8100 cal. BP based on 2262 high resolution shoreline altitude measurements.
